Redefining the Portable Camera Sony Black Card Mini RX Evaluation

IT168 evaluation from lulai 35, Ricoh GR and kangtaishi T3 in the film age to various small cards in the digital age, the portable camera has always occupied a very important position in the camera market because of its portability and image quality and performance not inferior to those of professional (large) cameras.

obviously, once Sony RX was released, it was "seriously up to standard" in terms of portability.

So, can this little guy with a 1-inch sensor meet the needs of photographers and photographers in terms of image quality and function? What exactly is the positioning of RX? This is the question that needs to be answered in this evaluation.

Advantages

1. Small size, light weight and good workmanship, suitable for EDC (daily carrying);

2. The overall performance of image quality is good, especially in the backlight scene;

3. The extreme night environment with high frame rate (slow motion) is still available.

Regret:

1. The usage scene is limited (no long exposure, no close-up function, no AF-C continuous focusing, 4K in inorganic).

Summary:

It is true that the quality performance of Sony RX is still good. But it must be said that the limitations of Sony RX are still many.

It is almost doomed that RX is a product that makes people "love to death, hate to death".

as a consumer, what we should do at this time is to keep calm and recognize our own needs.

if you want to use the RX to shoot the scenery for a long time and test the poison of the food, then I suggest looking at something else ..... RX is not used like this.

However, if you need a small camera that is not cumbersome to go to work every day, can go up the mountain and go to the sea, has professional picture performance and can occasionally play and upgrade, then Sony RX may be a better and more stylish choice than GoPro.

Redefining the design comments of the portable camera Sony RX

Sony RX weighs only 11g and measures: 59mm x 4.5mm x 29.8mm, which is the size of an egg. Compared with the so-called "portable machine" the size of a wallet, it really makes people feel that this is the real portable machine.

the p>RX fuselage is made of a large number of metal materials, which supports waterproof, shockproof and dustproof, giving people the feeling of solid materials and solid workmanship as soon as they get started.

▲ Front of Sony RX fuselage

▲ On the back of Sony RX fuselage, four direction keys, enter keys and menu keys are arranged along the lower right corner.

▲ The Zeiss small blue label on the left is a coquettish one, and the small hole is a wristband hole.

▲ The battery compartment is located on the right side of the fuselage, and the battery can be replaced.

▲ The black button on the left side of the top of the fuselage is the power button, and the red button on the right side is the shutter button. Shutter key is a two-stage design, half press focus and full press release shutter.

▲ tripod interface at the bottom of the fuselage

▲ The metal on the surface is angular, non-slip and textured.

▲ Unfortunately, the screen does not support touch operation.

▲ There are mini HDMI, Micro USB charging interface, microphone interface and TF card slot on the left side of the back. It should be mentioned that this card slot has no foolproof design, so don't insert it in the wrong direction as I did ......

▲ The front of the lens is protected by a glass cover, and the coating is green and has an anti-fingerprint coating. This glass cover can be replaced, and the official price is 72 yuan.

▲ The battery model used is NP-BJ1

▲ The battery specification is 3.7V 7mAh

Generally speaking, the product design of RX is very distinctive, and the volume is extremely small. At the same time, RX is made of real materials and solid workmanship. At least from the outside, the price of 4,999 yuan won't make you feel worthless.

There is no surprise that p>ISO16 is available. Sony RX high-sensitivity evaluation

The high-sensitivity performance of the camera is directly related to the night scene and sports shooting ability of the camera. The better the camera's high-sensitivity performance, the higher the image quality in dark light, and the stronger its ability to capture moments.

Sony RX is equipped with a 1-inch stacked sensor with 15.3 million pixels. It is reasonable to say that the image quality at high sensitivity should be better than that of ordinary card cameras. Let's take a look at the actual performance of RX.

put the camera on a tripod, turn off all internal noise reduction optimization, and directly output JPEG files. Take a 1% enlarged screenshot of the position shown in the red box below each ISO file.

as you can see, the picture quality of Sony RX has little difference from ISO8 (extended) and ISO1 (extended) to ISO125 (native lowest) and ISO2, and there is almost no difference in noise control and picture details. However, from ISO4, it can be clearly seen that the straight lines in the picture began to become rugged, and the picture quality began to decline. From ISO4 to ISO16, the noise in the picture increases gradually, but the loss of details is acceptable; Until ISO32, the details and noise of the picture suddenly became uncontrollable, and the picture also entered the range that was not recommended.

Sony RX high-definition image quality comments:

Generally speaking, for a camera with 1-inch film, the availability of ISO16 should be an 8-point score, which is good but not too bright. RX, as an experimental product, didn't surprise us in terms of high sensitivity.

redefining the analysis and evaluation of Sony RX lens

If the high-sensitivity performance determines the usability of a camera, the resolution determines the expressiveness of a camera.

Sony RX is equipped with a Zeiss equivalent fixed-focus lens of 24mmF4, with T-star coating of Tessar structure. With the performance of the 1-inch 15.3 megapixel sensor, we still look at the real shot.

We fixed RX on a tripod, ISO125 (native minimum), and the maximum size was optimal JPEG straight out. Take a 1% enlarged screenshot of the center and corners below.

▲ Original image

▲ 1% enlarged screenshot of Sony RX center

▲ 1% enlarged screenshot of Sony RX edge

As you can see, the resolution of Sony RX center and edge is not bad, and the house has sharp edges, clear texture and no visible purple edge. Generally speaking, the quality of RX can't compare with micro-single, but it's no problem to win GoPro.

redefining the glare performance test of the portable camera Sony RX

In addition to the analytical power in conventional scenes, the performance of the lens in extreme environments, such as large backlight scenes, is the key point that distinguishes the RX from mobile phones and sports cameras. After all, at present, the vast majority of mobile phones and sports cameras are still "dying at the sight of light", and once they are backlit, they become the scene of a car accident.

The performance of Sony RX in backlight is very good. Judging from the actual shooting samples, there is no glare or ghost in the picture, which is probably the contribution of Zeiss' T-star coating. On the other hand, the dynamic range performance of the camera is obviously not comparable to that of the mobile phone. The highlights are layered and colored, and there is no dead white.

It can be said that the lens of Zeiss, T-star coating and Sony's CMOS give RX an excellent backlight performance.

Redefining the video experience of the portable camera Sony Black Card RX

Sony RX does not support internal recording of 4k video, so it becomes boring to test the normal video capability of RX in normal scenes. However, RX simply supports slow-motion video shooting at up to 1fps. I am very interested to see the upgraded video performance of this 1-inch CMOS in low light.

upgraded video is different from ordinary video, which requires a high shutter speed for each frame. For example, the shooting format of 25fps(1 times slow motion) used this time requires a shutter speed of at least 1/25 s.. In this bad lighting condition, if you want to get such a high shutter speed, you need a very good high-sensitivity performance of the camera.

The following slow-motion video was shot with Sony RX

Although many mobile phones also have high frame rate function now, due to the limited high sensitivity of the mobile phone itself, the high frame rate mode usually cannot be turned on directly in this dim environment.

Sony RX can. When the automatic ISO can't meet the exposure requirements, the author forcibly raised the ISO to 128, so it can be exposed normally. At this time, it is true that the picture quality is very general, but objectively speaking, it is rare to photograph such extreme light conditions. Moreover, from the actual use scene, most of these creative videos are just for sending small videos of friends, and the picture quality is enough.

Redefining the black card mini RX real proof of the portable camera

The last old rule is the proof time.
